Eukaryotes - Kingdom Fungi
- Heterotrophic decomposers
- Attach to and break down solid substrates to recycle nutrients back into the environment
- Most common in estuaries, marshy areas, and mangrove forests
- Important in mangrove forests – first to colonize fallen leaves
- Many are pathogenic – even the ones that are normally terrestrial can infect other marine organisms
- Some have mutualistic relationships – fungi-infected algae are protected from invertebrate consumers
- Halocyphina villosa is a marine Basidiomycotina common on mangrove substrata
- Verruculina enalia, is one of the most dominant marine fungi to colonise woody mangrove substrata.
- Lutworthia sp. is a marine Ascomycotina usually associated with leafy mangrove substrata.
